YouTube Live view with Nikon D5100

I am trying to use a D5100 HDMI out as a live view input to YouTube through an encoder. I know that the live view is working properly as I log into the encoder and can see the live feed using VLC and other video players on my computer. Unfortunately, YouTube does not recognize the feed because the input settings are not set up properly. Does anyone know the HDMI output parameters? I need to know any video format information that you might know, but would like to know the following when set to 720P out: FPS (frames per second), GOP (Group of Pictures), CBR bitrate (kbps), and actual 720P resolution (1280 X 720?).
